The EOSINT M 270 builds metal parts using Direct Metal Laser-Sintering (DMLS). The technology fuses metal powder into a solid part by melting it locally using a focused laser beam. The parts are built up additively layer by layer. Even highly complex geometries can be created directly from 3D CAD data, fully automatically, in just a few hours and without any tooling. It is a net-shape process, producing parts with high accuracy and detail resolution, good surface quality and excellent mechanical properties. A wide variety of materials can be processed by the EOSINT M 270, ranging from light alloys via steels to super-alloys and composites. EOS has developed novel alloys especially for the DMLS process, and has also optimized and qualified standard industrial materials such as stainless steels for this machine.




The EOSINT M 280 is an updated and improved version of the EOSINT M 270. It directly produces top-quality metal parts on the basis of three-dimensional CAD data – fully automatically, in only a few hours, and with no need for tools. The system is optionally equipped with a solid state laser of either 200 or 400 watt, which operates in both protective nitrogen and argon atmospheres. This allows the system to process a wide range of materials: from light metals to stainless and tooling steel to super alloys.

For the EOSINT M 280 EOS offers a number of powdered metal materials with corresponding parameter sets that have been optimized according to the application. The distinctive features of the EOSINT M 280 system are the quality of the parts it produces and the ergonomically designed peripherals. These features are what make the system the ideal production tool for the economical batch-size optimized manufacture of parts at all stages of the product life cycle.





The EOS M 290 is an enhancement of the well-known EOSINT M 280, the leading system on the market for the tool-free manufacture of serial components, spare parts and functional prototypes directly in metal. The system is equipped with a 400-watt fibre laser. This type of laser provides an exceptionally high beam quality combined with performance stability. The EOS M 290 operates in protective nitrogen as well as argon atmospheres. This allows the system to process a wide range of materials. Extensive monitoring features take quality management to a new level and comply with the requirements of industrial production.

A recirculating filter system with automated self-cleaning allows for fewer filter changes and longer lifetime. This significantly reduces filter costs. Job preparation and calculation is separated from the building process: the job file prepared at your desk is transmitted via the network; the system focusses entirely on building parts. This provides great flexibility and efficiency for application development which can be done offline as the system remains free for building. With the fast offline job preparation feature, users can quickly handle complex parts and large job files.





With a building volume of 400 x 400 x 400 mm, EOS M 400 allows the production of large metal parts on an industrial scale – directly from CAD data and with no need for tools. A 1 kW laser boosts productivity due to higher build rates and increased layer thickness. Recoating with powder material from both sides reduces non-productive time. EOS M 400 consists of a Process Station and a Setup Station. This modular approach facilitates the easy integration of future innovations.

Extensive monitoring features take quality management to a new level. A camera integrated into the process chamber monitors the powder bed by taking single images — after recoating and after exposure. Parameters such as position of z axis, laser power, scanner position, humidity, temperature and pressure are monitored continuously.
